I bought the 45ACP/45 Colt Redhawk about a month ago. I shot 6 moon clips of 45ACP, with two of the moon clips after 1 or 2 shots the cylinder wouldn't advance. I opened the cylinder and pushed down on the moon clip, shut the cylinder and the rest of the cartridges fired just fine. The other 4 moon clips all worked ok with no problems.
I found TK Custom and they make moon clips for the Redhawk model 5032. They are supposed to be better metal than the Ruger moon clips. I measured the thickness of the Ruger moon clips and they varied from .030" to .0335". The TK moon clips measured .033 and they all measured the same. So I'm thinking the problem is with the moon clips. I have Wed. off this week and will hit the range and see how the TK moon clips work. I also sorted the Ruger moon clips and will try the .031" and .033" ones and see how they work. I'm also taking 3 different brands of ammo to see if there is an issue there. I'll report back after my trip to the range.
I bought the Redhawk because I wanted to experiment with Colt 260gr to 300gr heavy loads. It shoots 45 Colt just fine. I'm still glad that I bought the Redhawk!! I have a Blackhawk 45ACP/45 Colt convertible that shoots both calibers just fine.
Here's a picture of the moon clips. The Rugers are on the right and the TK are on the left.
